they are kinda the same
so BL is more like -18 comics they show some skinship and hints of sex sometimes but with no details and they focus more on the plot and the emotion part (the type of BL i read)
and YAOI +18 which is the most popular it's focused on the sex and sometimes the plot (it depends like the other person said the most popular yaoi they have a good plot)
the one who's dead are yaoi mangas since they are short and everyone even japanese are into webtoons
and tbh Yaoi is the most used term some ppl they explain BL as "yaoi with no sex" but yea it's practically same sex relationship in both styles ^^
I am chill :D
But yaoi doesn't have plot but BL does. BL has sex scenes lmao, but also plot and character development(example: painter of the night, BJ Alex, walk on water and so many other.. they have a lot of sex scenes but also plot)! Meanwhile yaoi only sex :/.
For potato!
Yea, yaoi doesn't have plot and most of them are kinda unhealthy(rape, pedophilia..) but there and some that are okay ig. And yes people are using terms Yaoi because they arent educated on that topic and because they are probably reading on illegal sites (just like we do),, but on legal sites, so called "Yaoi" genre is called BL and that is correct

i will gladly answer your last question Ham
all you have to do is TO START NOTICING HIM AND START LOVING HIM
